280 PointsinitWithObjects problem
I can't complete the task. It requires me to add 'toothpaste' 'bread' and 'eggs' into the array shoppingList. I dont know where the problem is. It looks okay.
Thanks.
#import "UIViewController.h"
@interface ViewController : UIViewController
@property (strong, nonatomic) NSString *shoppingCart;
@property (strong, nonatomic) NSArray *shoppingList;
@end
#import "ViewController.h"
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Add your code below!
[self.shoppingList initWithObjects:@"toothpaste",@"bread",@"eggs",nil];
}
@end

14,477 PointsLooks like there is a bit of an error over in your ViewController.m file. Down where you have
[self.shoppingList initWithObjects:@"toothpaste",@"bread",@"eggs",nil];
In order to init your shopping list, you need to specifically init it to a NSArray object. Like this!
self.shoppingList = [[NSArray alloc] initWithObjects:@"toothpaste", @"bread", @"eggs", nil];
Your header file knows the shopping list is going to eventually have an NSArray object in it, but in your implementation you'll need instantiate a new array to that object. I hope that doesn't sound too confusing! The header file creates the shoppingList variable, and in your implementation you need to assign an NSArray to it :)
